Description

Technical Field

[0001] The present invention relates to the technical field of inductor parts, in particular to an inductor coil skeleton. Background Art

[0002] Smart power distribution systems include various types of inductors, such as those used for filtering, current limiting, and reactive power compensation. During the manufacturing process, these inductors require an inductor bobbin to support and secure the inductor coils, ensuring stable and reliable performance. For example, high-frequency inductors are often used in power electronics devices in power distribution systems to filter high-frequency noise from the power supply. These high-frequency inductors' coils must be wound on a specific inductor bobbin to ensure excellent high-frequency characteristics and electrical performance.

[0003] When the current passing through the inductor coil exceeds its rated current, the coil will heat up due to the excessive current. If overloaded for a long time, the heat will continue to accumulate, and the inductor coil will be at risk of overheating and damage. The excessive heat will also burn the frame together.

[0028] The present invention provides a technical solution: Figures 1-8 An inductor coil skeleton shown includes a disk 1 and a disk 2 4, with multiple arc plates 3 fixedly connected in a circular array between disk 1 and disk 2 4.

[0030] The flow control mechanism includes a connecting ring 30, a chute 26 and a temperature sensor 14. The connecting ring 30 is fitted on the inner wall of the splicing tube 15. A sealing mechanism is provided between the connecting ring 30 and the inner wall of the splicing tube 15. The chute 26 is opened on the outer wall of the splicing tube 15, and a sliding rod 19 is fitted in the chute 26. One end of the sliding rod 19 is fixedly connected to the outer wall of the connecting ring 30, and the other end of the sliding rod 19 is provided with a driving mechanism, and an alarm mechanism is provided between the sliding rod 19 and the splicing tube 15, and an arc-shaped baffle 11 is fixedly sleeved on the outer wall of the sliding rod 19. The inner arc surface of the arc baffle 11 fits with the outer wall of the splicing tube 15, and the temperature sensor 14 is fixedly connected to the inner arc surface of one of the arc plates 3 near the disc 2 4.

[0031] The flow control mechanism also includes a plurality of fixed tubes 13, one end of which is connected to the outer wall of the splicing tube 15 in a circular array, and the other end of the plurality of fixed tubes 13 is connected to a hose 20. The ends of the plurality of hoses 20 away from the fixed tube 13 are connected to a connecting tube 6. The outer walls of the plurality of connecting tubes 6 are provided with an air injection groove 7, and each connecting tube 6 corresponds to the gap between two adjacent arc plates 3.

[0032] The sealing mechanism includes a fixed block 33, which is fixedly connected to the inner wall of the splicing tube 15 near the gas tank 12, and a guide column 32 is slidably inserted into the inner wall of the fixed block 33, and one end of the guide column 32 is fixedly connected to a frustum 31, and the conical surface of the frustum 31 fits tightly with the inner ring surface of the connecting ring 30, and a spring 2 34 is fixedly connected between the frustum 31 and the fixed block 33, and the spring 2 34 is slidably sleeved on the outer wall of the guide column 32.

[0033] The driving mechanism includes a support plate 23, which is fixedly connected to the outer wall of the gas tank 12, and a motor 24 is fixedly installed on the upper end of the support plate 23, and a stud 21 is fixedly connected to the output shaft end of the motor 24. The end of the stud 21 away from the motor 24 is rotatably connected to the disc 24, and the outer wall of the stud 21 is threadedly sleeved with a ring 22, and the outer wall of the ring 22 is fixedly connected to the other end of the sliding rod 19.

[0034] The alarm mechanism includes a trigger column 18 and two L-shaped rods 16. The trigger column 18 is fixedly connected to the side wall of the sliding rod 19 corresponding to the disc 2 4. The two L-shaped rods 16 are fixedly connected to the outer wall of the splicing tube 15 symmetrically up and down, and a small alarm 17 is fixedly connected between the two L-shaped rods 16. The trigger end of the small alarm 17 corresponds to the trigger column 18.

[0035] The side wall of disk 1 corresponding to disk 2 4 is fixedly connected with a torsion spring 10, and the end of the torsion spring 10 away from disk 1 is fixedly connected with a collar 8. The torsion spring 10 and the collar 8 are both slidably mounted on the outer wall of the gas tank 12. The outer wall of the collar 8 is fixedly connected to the outer walls of the multiple connecting pipes 6, and the outer wall of the collar 8 is fixedly connected to the limit block 25. The upper end of the limit block 25 is fitted with an L-shaped plate 9, and the end of the L-shaped plate 9 away from the limit block 25 is fixedly connected to the top of the outer wall of the ring 22.

[0036] Working principle: The skeleton of the inductor coil is as follows: Figure 1 As shown, the inductor coil is wound around the outside of the plurality of arc plates 3. After the device is installed, when the inductor coil is overloaded and the temperature exceeds the safe temperature, the temperature sensor 14 will sense the temperature at this time. Since the temperature sensor 14 is electrically connected to the motor 24, the motor 24 will be started, and the motor 24 will drive the ring 22 to move toward the disk 2 4. The ring 22 will drive the sliding rod 19 to slide in the slide groove 26 on the splicing tube 15. The sliding rod 19 will drive the connecting ring 30 to slide in the splicing tube 15 toward the pipe cover 5. Under the action of the spring 2 34 (the spring 2 34 is originally in a squeezed state), the table 31 will be driven to move toward the pipe cover 5, and the table 31 will also drive the guide column 3 2 slides in the fixing block 33 (the limit distance of the movement of the round table 31 toward the pipe cover 5 will not allow the guide post 32 to slide out of the fixing block 33) until the sliding rod 19 slides to the other end of the slide groove 26. At this time, the connecting ring 30 will also move multiple fixed pipes 13, and the motor 24 will stop running. At this time, a gap will be left between the connecting ring 30 and the round table 31, and at this time, under the action of the multiple springs 1 28, the sealing disk 27 will be driven to slide quickly in the direction of the splicing pipe 15 (it should be noted that when the connecting ring 30 is in close contact with the round table 31, the space between the sealing disk 27 and the connecting ring 30 is filled with inert gas that has been treated at low temperature. At this time, under the action of gas pressure, the sealing disk 27 will always remain as shown in FIG. Figure 5 In the state shown, the sealing disk 27 will continue to squeeze the multiple springs 28).

[0037] Then the low-temperature inert gas will be quickly pushed into the multiple fixed tubes 13, the multiple hoses 20 and the multiple connecting tubes 6 in turn, and finally the inert gas will be quickly ejected from the multiple jet slots 7 on the multiple connecting tubes 6. Since each connecting tube 6 corresponds to the gap between two adjacent arc plates 3, the low-temperature inert gas will quickly contact the inductor coil, and quickly cool the inductor coil in the first time. The inert gas will flow around the inductor coil and around the disc 1 1, the disc 2 4, and the multiple arc plates 3 for a period of time. According to the characteristics of the inert gas, the fire source can be suppressed, which can not only prevent the inductor coil from being overheated and damaged in the first time, but also prevent the disc 1 1, the disc 2 4, and the multiple arc plates 3 used to support the inductor coil from being overheated and burned, thereby delaying the fault deterioration process by valuable time.

[0038] It should be noted that when the sliding rod 19 moves toward the disk 2 4 , it also drives the arc baffle 11 to slide on the outer wall of the splicing tube 15 . The arc baffle 11 can suppress the chute 26 from being sealed and prevent the inert gas from being discharged along the chute 26 .

[0039] It should also be noted that when the sliding rod 19 moves toward the direction of the disk 2 4, it will also drive the trigger column 18 to move together. When the sliding rod 19 slides to the other end of the slide groove 26, the trigger column 18 will be driven to squeeze the trigger end of the small alarm 17, thereby triggering the small alarm 17 to sound an alarm, so as to notify the staff to turn off the corresponding power supply as soon as possible, stop the loss in time, and ensure the safe operation of the intelligent power distribution system.

[0040] It should also be noted that when the ring 22 moves toward the direction of the disk 2 4, it will also drive the L-shaped plate 9 to move together, and the L-shaped plate 9 will leave the upper end of the limit block 25. At this time, under the force of the torsion spring 10 (the torsion spring 10 is originally in a twisted state), the torsion spring 10 will rotate forty-five degrees clockwise, thereby driving the collar 8 to rotate forty-five degrees clockwise outside the gas tank 12. The collar 8 will drive the multiple connecting pipes 6 to rotate forty-five degrees clockwise together. The inner ring surface of the collar 8 is made of rubber material, so there is a gap between it and the gas tank 12. Under the action of the friction force, the rotation speed of the gas tank 12 will not be very fast, but will be in slow rotation, and finally drive the multiple connecting pipes 6 to rotate to correspond to the hole slots 2 on the multiple arc plates 3 respectively. Then, the inert gas ejected from the multiple jet slots 7 on the multiple connecting pipes 6 will also pass through the multiple hole slots 2 to further contact the inductor coil, thereby improving the distribution uniformity of the inert gas around the inductor coil and around the disc 1 1, the disc 2 4, and the multiple arc plates 3, more evenly cooling the inductor coil and more comprehensively suppressing the fire source.

[0041] It is worth mentioning that when it is necessary to refill the interior of the gas tank 12 with inert gas, the disc 1 1, the disc 2 4 and the multiple arc plates 3 can be detachably connected by screws, which will not be described in detail. Then all the components can be easily reset first, except that the sealing disc 27 will always be in a state close to the splicing tube 15 under the action of the spring 1 28. Then the pipe cover 5 is unscrewed, and the hard pipe for conveying low-temperature inert gas is inserted into the inside of the splicing tube 15 and tightly against the connecting ring 30. Then, the inert gas can break open the cone 31 during delivery, and the cone 31 will squeeze the spring 2 34. Then, the low-temperature inert gas will enter the gas tank 12 along the cone 31 and the connecting ring 30. Under the action of air pressure, the sealing disc 27 can be pushed away from the splicing tube 15. The sealing disc 27 will squeeze the multiple springs 1 28, and the air between the sealing disc 27 away from the wall of the splicing tube 15 and the gas tank 12 will be squeezed out along the air pipe 29 until the sealing disc 27 is as Figure 5As shown, the delivery of the low-temperature inert gas is stopped and the delivery pipe is pulled out. At this time, under the force of the second spring 34, the round table 31 will automatically seal the connecting ring 30, thereby facilitating the storage of the low-temperature inert gas for next use.

[0042] It should also be noted that the outer ring surface of the sealing disk 27, the conical surface of the truncated cone 31, and the inner arc surface of the arc-shaped baffle 11 are all provided with a rubber layer, all for achieving a better sealing effect.
